RabbitMQ versions from 3.13.0 up to but not including 3.13.18, 4.0.23, 4.1.14, 4.2.9, and 4.3.3 have a vulnerability in their native MQTT and MQTT over WebSocket implementations when used behind a trusted PROXY Protocol frontend. The issue causes the proxy-derived client address to be lost before the MQTT authentication checks loopback_users, allowing the frontend-to-broker address to be treated as loopback. This enables an attacker with valid credentials for a loopback-restricted account to bypass source-address restrictions, though password authentication is still required. The vulnerability is fixed in the specified patched versions. Join the discussion | GCVE Database | 09/25/2026, 17:17:00 UTC Added: 10/17/2026, 22:24:39 UTC |
